Easytrak Nexus 2, Model 2692

The Nexus 2 is the second generation of Easytrak digital USBL systems designed as a highly advanced positioning and tracking system that is quick to deploy and straightforward to operate. Featuring AAE Sigma 2 acoustic protocols, the Nexus 2’s digital Spread Spectrum transmissions provide a secure acoustic link with very low susceptibility to interference, enabling precise and reliable positioning over an extended operational range.

Intuitive control software, bringing the confidence of professional USBL systems to a wide operator base.

Four commercial versions of the system are available; the rack-mount, vessel based Nexus and Lite, the compact Alpha and Alpha Portable that have a display screen and keyboard housed in a marine grade splash-proof enclosure.

Positioning Beacons

Every beacon Applied Acoustic's manufactures has been designed to be immediately compatible with almost all industry standard tracking systems operating worldwide.

Micro Beacons: Small sized, ideal for divers, short ranges and small ROV’s

Mini Beacons: ‘Work-horse’ beacons for towfish and ROV tracking, often used by divers too

Midi Beacons: High powered, but compact. Used for long range towfish tracking and AUV positioning

Fat Boy Beacons: Ideal for deep water ROV’s and AUV’s

Low Frequency Beacons: Long range, deep water applications

Seabed Beacons: Large battery capacity for long term deployment often used as reference markers

Sub Bottom Profiling

Applied Acoustics manufactures a variety of sub-bottom profiling systems to accommodate different challenges such as coastal or deep waters, soft sediment or harder rock. A typical sub-bottom profiling system will consist of:

Energy Source

Sound Source

High Voltage Cable

Hydrophones

Acquisition system

Sub-bottom profiling systems from Applied Acoustics use the technique of Reflection Seismology to create a 2D picture of the geology beneath the seabed. This technology requires a controlled seismic source of energy (a CSP unit) connected by high voltage cable to a sound source (boomer or sparker) that transfers the energy through the water to penetrate the seabed.
